I HAVE A GSR MOTOR IN 96 COUPE, I BOUGHT A NEW GSR HEAD AND HAD VALVES SPRINGS AND RETAINERS INSTALLED IN IT. PUT THE NEW HEAD ON THE CAR WITH STAGE 2 SKUNK CAMS ALONG WITH CAM GEARS. THE CAR DRIVES FINE UNTIL 5000 RPMS WHEN VTEC HITS. CAR LOSES POWER AND MAKES A FLUTTER NOISE. TRIED REPLACING VTEC SELONOID, NOT IT. IF YOU UNPLUG VTEC CAR DRIVES FINE WITHOUT VTEC. IM GUESSING IT'S SOMETHING WITH THE VTEC ROCKERS, ANYONE HAD THIS KIND OF PROBLEM OR HEARD OF ANYTHING LIKE IT?? IVE BEEN TOLD MAYBE THE ROCKER SHAFT IS INSTALLED BACKWARDS.
